Org selection is not calling out to the external ROR API

[briri]

Please complete the following fields as applicable:

What version of the DMPRoadmap code are you running? (e.g. v2.2.0)
v3.0

Expected behaviour:
When you type in the 'Organisation' typeahead box on the 'Create Account' form it should search the local DB for results and call out to the ROR API

Actual behaviour:
It only checks the local DB

This appears to be related to the switch over to Strong Params during the Rails 5 upgrade. The incoming data in the POST come through as:

Processing by OrgsController#search as */*
  Parameters: {"org"=>{"name"=>"National"}, "funder_only"=>"false", "type"=>"combined"}

But the controller is expecting the :funder_only and :type to be encapsulated in the Strong Params: {"org"=>{"name"=>"National","funder_only"=>"false","type"=>"combined"}

Works for me - looks initially at the local institutions I'd expect to show up and then comes up with a very long list from ROR.

When searching for orgs in the contributors tab I'm seeing orgs not already in the db, so can confirm that it is working.
